If you are not sure what to use to put out a hazardous material fire, what should you do?

Wait for qualified fire fighters
Use water immediately
Attempt to put out the fire with any available material
Call the police for assistance

The correct answer is: Wait for qualified fire fighters

Waiting for qualified firefighters is the safest and most appropriate response when you're uncertain about how to handle a hazardous material fire. Hazardous materials can react unpredictably depending on their chemical composition, and using the wrong method to extinguish such fires may result in more danger, potentially causing explosions or releasing toxic fumes. Qualified firefighters are trained to handle these situations with the right tools and knowledge of the necessary safety precautions. Using water immediately can be dangerous, as certain hazardous materials may react violently with water, leading to increased risk. Attempting to extinguish the fire with any available material can worsen the situation and is not advisable without proper knowledge of the chemicals involved. Calling the police may not provide the immediate specialized help needed for a hazardous material fire, as they are not equipped like firefighters to handle these specific incidents. Therefore, relying on trained professionals is the best course of action.
